Division 7 EXPRESSION OF RESULTS

The method of calculation and formula specific mass of the sample is expressed in g/ml of skimmed milk at 20 ^oC according to the following formula:

$$\frac{\mathrm{1\; 000}\mathrm{·\; mv\; -\; MG\; ·\; mv}}{\mathrm{1\; 000}-\frac{\mathrm{MG\; ·\; mv}}{\mathrm{0,92}}}=\frac{\mathrm{0,92\; mv}\left(\mathrm{1\; 000}\mathrm{-\; MG}\right)}{\mathrm{920\; -\; MG\; ·\; mv}}$$

where

mv

the specific mass of the sample read on the hydrometer (5.4) in g/l

MG

the fat content of the sample in g/1

0,92

the density of fat.
